'LINING FOR REFRIGERATORS.

Specification of Letters Patent.

Patented July 5, 1910.

Application filed February 21, 1910. Serial No. 545,038.

ing for refrigerators which shall be effective for the purpose and comlete in itself, with a shelf support and t e remaining parts allproperly bracedand held in position.

A further object is to provide in an enameled refrigerator or sheetmetal refrigerator lining, an improved construction of shelf support.

A still further object is to provide an improved flange construction forsheet metal refrigerator lining which shall effectively brace thevarious parts.

I accomplish the objects of my invention by the devices and meansdescribed in the following specification.

The invention is clearly defined and pointed out in the claims.

A preferred embodiment of my invention is clearly illustrated in theaccompanying drawings, forming-a part of this specification, in which,

F igure l'is a perspective view of my improved refrigerator lining laiddown upon its back, the bottom portion being toward the right. Fig. 2 isan enlarged detail of the flange and shelf support, showing the relationof the same. Fig. 3 is a detail seetional view on line 33 of Fig. 1.Fig. 4 is an enlarged detail view of a modification of the structureappearing in Figs 1, 2 and 3. Fig. 5 is a detail sectional view of thestructure appearing in Fig. 4:, taken on a line 5-5 of Fig. 4. Fig. (5is a detail view of the blanks fronrwhich the structure appearin inFigs. 4 and 5 are formed. Fig. 7 is a re uced detail front view of myimproved refrigerator lining showing the exact relation of the variousparts when looking into the front of the refrigerator.

In the drawings, similar reference numerals refer to similar partsthroughout the several views, and the sectional views are departing frommy invention.

taken looking in the direction of the little arrows at the endsofthesection lines.

Referring to' the numerals of reference, the improved sheet metalrefrigerator lining 1 is provided with sides 2 in which are formedcorrugations 3, 3 for the shelf su port.- Up and down the side 2 andsecuring t 1e same rigidly in position is a flange l, which flangeextends substantially around the refrigerator, and may be turned eitheroutwardly or inwardly, as the case may be. It ordinarily is preferred toturn the flange inwardly or upwardly at the bottom of the refrigeratorso that it serves to collect any moisture at that point, although it isoftendesirable to turn it outwardly or downwardly so that the moisturewill readily flow out at the front and can readily be wiped off.

The flange t may be a strap of metal, as indicated in Fig. 2, which iswelded, preferably by oxyhydrogen welding, at 5, 5 to the sides of therefrigerator lining at different points. It is, of course, strongest andbest if the welding extends the entire length of the joint, but it isfound not to be really necessary, for if the welding occurs atintervals, as indicated in Fig. 2, the enamel flows between the partsfor the balance of the way, making a practically complete flange.

'lhe flange may be formed as appears in Figs. 4:, 5 and 6 by turningover the edge of the sheet metal, after cutting a slit 9 to permitof thefolding of the corrugation 3 for the shelf support. A portion, as 8, isthen cut out opposite this point and the two portions, (3, (5 weldedtogether at 7, as indicated in Fig. l. The flange is cut loose by a slit1), as seen in Fig. 6. Openings 10 and 11, ll are in the top of therefrigerator liningto perinit of circulation of cold air from the icechamber above. A corrugation 12 is usually formed in the bottom,terminating in an outlet nozzle 13 for the discharge of the drip. Thefront end of this corrugation is closed by a projection lat of theflange .4: at that point.

Having thus described my improved sheet metal enameled refrigeratorlining, I desire to say, as appears from the description, that this canbe considerably modified Without The parts might be entirely pressed outof sheet metal but that will be found objectionable in that where thecorrugation for the shelf support is formed, unnecessary stress will beput upon the metal, and extra expense will be in- Having thus describedmy invention, what.

I claim as new and desire to secure by Letters Patent is:

' 1. In an article of manufacture, a reirigcrator lining of sheet metalcontaining corrugations at the sides for forming shelf supports, and aflange extending across the said corrugations and welded thereto, toreinforce and support the same, as specified, thewhole being suitablycoated with enamel, as specified.

2. In an article of manufacture, a re frigerator lining of sheet metalcontaining corrugations at the sides for forming shelf supports, and aflange extending across the said corrugations to reinforce and supportthe same, as specified, the Whole being suitably coated with enamel, asspecified.

3. ,In an article of manufacture, a refrigerator lining of sheet metalcontaining corrugations at the sides for forming shelf supports, and aflange extending across the said corrugations to reinforce and supportthe same, as specified.

4:. A sheet metal refrigerator lining with shelf supports formed thereinand supported by a suitable welded flange extending across the saidsupports and around the front of said lining, the joints of thestructure being welded and the whole being suitably coated with enamel,as specified.

In witness whereof, I have hereunto set my hand and seal in the presenceof two Witnesses.
